This dataset holds different soil samples from the refugee area Nakivale in the South of Uganda. We collected and analyzed the samples during the project Framework for Assessing, Monitoring and Evaluating the environment in refugee-related operations (FRAME) in 2010.

Catch numbers data collected from a bottom trawl survey series: Trawl positions, duration and gear parameters; catch statistics of the target species; length frequency distributions; age, sex and maturity. The target species are: cod, haddock, whiting, saithe, hake, black and white-bellied anglerfish, megrim, plaice, sole, herring, blue whiting, mackerel, horse mackerel, blonde ray, cuckoo ray, spotted ray and thornback ray. Data coverage has been for the waters around Ireland from 10m to 180m in depth (Irish Sea, Celtic Sea, West and North of Ireland). The spatial coverage has varied from year-to year. The sampling locations have been selected from known fishing tracks while trying to ensure maximum spatial spread over the survey area. The surveys took place in February-March of 2004-2009. Samples were collected using a GOV bottom trawl (a scaled-down version of the IBTS standard, see: Manual for the International Bottom Trawl Surveys, ICES Survey Protocols SISP 1-IBTS VIII). The main purpose of the survey was to collect information on the length and age at which target species first reach maturity in the waters around Ireland. The surveys were carried out by the Marine Institute (Ireland) Fisheries Science team. All data collected on the survey are available.

Data collected includes the following: Densities of yellow eel, juvenile salmon and juvenile trout at 40-50 sites, fish (per m2) and lengths of individual fish. Data collected from the Burrishoole catchment rivers and lakes within Furnace Newport Co. Mayo. Data surveys have taken place annually since 1959. Data surveys have involved surveys of salmon and trout stocks taking place in the rivers and main lakes of the catchment. Electrofishing, with 3 fishing depletions, are used for salmonids in the streams and fine mesh beach seines are used in the lakes. Data has been collected to ascertain knowledge on the abundance of key target species in the Burrishoole catchment. Data originally collected by the Guinness Estate and more recently by the Marine Institute Newport facility team. Data is 100% complete for each year since 1959.

"Subfossil Tree Ring Measurements from L'Etang Majeur " is a tab delimited text file containing incrimental measurement values for individual samples of subfossil pine trunks submerged in L'Etang Majeur, Haut-Vicdessos, Midi Pyrenees. The data also includes tree ring measurements of selected live pines from around the lake shore.

Catch numbers per species from Irish Groundfish Survey haul stations. The Irish Groundfish Survey covers fisheries trawl stations in the North Atlantic Ocean, Celtic Sea, Irish Sea and Saint Georges Channel around Ireland. The Irish Groundfish Survey has been a two-legged survey taking place each October-December since 2003. Irish Groundfish Survey involved shot and haul stations at regular sites where fish species are caught and processed on board the Irish research vessel RV Celtic Explorer in the fisheries lab. The primary goal of the Irish Groundfish Survey has been to develop estimates of juvenile abundance for important fish species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance. In addition, the Irish Groundfish Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations. When these data are combined with annual recruitment indices they have helped identify the possible causes driving year-class success or failure, and allowed fisheries scientists to see long-term changes in populations that may have been caused by fishing, pollution, or climate change. The Irish Groundfish Survey feeds into the International Bottom Trawl Survey (IBTS) for international reporting. The Irish Groundfish Survey has been managed by the Fisheries Ecosystem Advisory Services (FEAS) section of the Marine Institute (Ireland). Data complete for each year survey has taken place.

Bathymetric data were acquired in Reao Atoll, a semi-enclosed atoll lagoon without reef pass but connected to ocean through numerous shallow spillways (known locally as "hoa") along its southern rim. This data was acquired as part of the GAIA (ManaGement strAtegy evaluatIon for small-scale fisheries in Atoll lagoons) project, which evaluates the sustainability of giant clam exploitation within the context of climate change. The lagoon of Reao is composed of three basins with varying depths (the NW basin being the shallowest and the SE basin the deepest). Bathymetric data were acquired from 29/04/2022 to 04/05/2022, within the lagoon with a Multibeam echo sounder IWBMS (NORBIT), and resampled at 5 m spatial resolution. Satellite-derived-bathymetry (SDB) at 10 m spatial resolution was established by coupling this bathymetric data with a Sentinel-2B image captured on 26/09/2020 and using the « Iterative Multi Band Ratio » technique (detailed methodology is described in Quéré et al. 2025). Finally, bathymetric surveys were carried out to characterize the nine most functional hoa of the atoll. One bathymetric survey was carried out in the longitudinal section of each hoa, while one or two surveys were carried out in their cross-sections.

Data of parameters presented as figures in the manuscript: Biogenic silica (BSi: µmol.L-1), Lithogenic silicon (LSi: µmol.L-1), Total Chlorophyll a (TChla: mg.m-3) and Fucoxanthin (Fuco: mg.m-3). Note that: - Total fraction for BSi and LSi is available from Niskin bottles (> 0.8 µm) and in situ pumps (> 0.45 µm); - Size-fractions for BSi and LSi is available from in situ pumps only (5-53 µm; > 53 µm); - Total fraction for TChla and Fuco is available from Niskin bottles (> 0.7 µm). - Integrated data (0-200 m) is available from Niskin Bottles. Acronym explanations: - Sampling type: ISP = In Situ Pump; ISP-SF = In Situ Pump with Size-Fraction; NSK = Niskin. - Method used for BSi and LSi computation: NOC = No Correction applied; RAG = Correction using the method used from the protocol established by Ragueneau et al. (2005); ACR = Average Crustal Ratio method used when one of the criterion from the protocol established by Ragueneau et al. (2005) is not respected. - bdl = Below Detection Limit For further explanations in the method, should you please refer to the Material and Methods section in the manuscript (revised version submitted in Marine Chemistry).

Gironde estuary environmental parameters and SPM maps generated from 41 Landsat-8/OLI and Sentinel-2/MSI images acquired over the period 2013-2018. Except bathymetry and daily river discharge data, that are accessible on public platforms, the dataset includes all of the time seris used in the publication: Analysis of suspended sediment variability in a large highly-turbid estuary using a 5-year-long remotely-sensed data archive at high resolution, Journal of Geophysical Research: Oceans, DOI:10.1029/2019JC015417.
